"Patented Mar. 4, 1930 UNITED STATES- PATENT OFFICE JAMES L. KING- AND ROBERT L. VANCIL, OF DARLINGTON, IDAHO; SAID KING ASSIGNOR T0 SAID VANCIL I SHEEP KNIFE Application filed April 10,

a This invention relatesto an improved implement especially designed for docking and castrating lambs. It is a matterof common knowledge that at a certain age it is custom- 5 aryto dock (that is to cut off the tailsjFof I antiseptic reasons it has-been found necessary to resort to repulsive methods in removing the testicles, and in some instances they are extracted with the human fingers- The latter method was found objectionable because of' infection resulting :from

the use of the fingers and undersome methods it is quite unhealthy and undesirable to most persons in carrying outthis work.

WVith this in mind we have evolved and pro duced a novel simplified, instrument which permits the operator to carry on the dockin and castration operation conveniently an with no loss of time. I v

In carrying out the invention we have constructed a form of instrument which comprises a handle, a knife, and a finger'man'iputhese features being arranged in intimate association to permit successive manipulation rapidly and with successful results.

working surface of this jaw is provided with purposes, it is employed by grasping the handle 3 firmly and forcibly swinging the knifeagainst the tail to cut it off at the point desired. The knife may also be employed for making an incision in the testicle casing, after which the clamping means may be brought into play for removing the testicles. This is done by placing the index finger beneath or around the stationary jaw 4;, and forcing the thumb against the bevelled surface 10 to cause the jaws to grasp the testicle to conveniently extract it.

An instrument constructed in accordance with the present invention will be found especially useful in fulfilling the requirements of a device of this class in a sanitary and efficient manner. The simplicity is such as to imake it unnecessary to enter into a more detailed description.

Minor changes 1n the shape, size, and rearrangement of detans coming within the field of invention claimed may be resorted to, in actual practice, if desired.

We claim:

' 1. A sheepknife comprising a handle, a pair of longitudinally spaced right angularly extending arms carried by said handle and bifurcated at their free ends, a knife disposed in spaced parallelism with said handle and fastened between the furcations, one end of said handle being fashioned to provide a stationary clamping jaw, and a relatively movable jaw pivoted on said handle and cooperable with said stationary jaw.

2. A sheep knife comprising a handle, one end of which isfashioned to provide a stationary clamping jaw, the working surface of said jaw being provided with'an antislipping means, a relatively movable block like jaw pivoted between its ends on said handle at the inner end of'said stationary jaw, said free end working surface of said movable jaw being provided with anti-slipq i I ping means and formed with a bevelledthumb surface;

3. A sheep knife comprising a handle, one end of which is fashioned to provide a:sta-

tionary clamping jaw, the workingsurface of said jaw being'provided with an antislipping means, a relatively movable block I like jaw pivoted between its ends on said handle at the inner end of said statio'na'ryrj aw,

of the movable jaw.

,In testimony whereof we natures.
